One of the first synthetic rubbers developed in the search for oil resistant rubber. Widely used due to its combination of useful properties and comparatively low price.Properties

resistant to a wide range of hostile environments

resistant to oils and chemicals

weather and water resistant

can withstand temperatures from -30°C to 95°C

easy to process and compound, offering cost benefits

flame retardant

can be produced in any colour required

Limitations

unsuitable for applications requiring contact with fuelstendency to tear once there is initial damage

some Neoprenes may crystallise during storage or use causing temporary stiffening (increase in modulus/hardness). If parts are deformed during crystallisation, they may take on a set. However, crystallisation is a readily reversible phenomenon and can be removed by warming over 80°C. It can be prevented by the use of special grades.

Typical Applications

most general mechanical applications without contact with fuel

particularly useful in marine environments due to good ozone resistance.
